線程「main」中的異常java.lang.NumberFormatException：對於輸入字符串：「npcId」 當我嘗試運行它時。我的代碼有什麼問題？在線程「main」java.lang.NumberFormatException中的異常：對於輸入字符串：「npcId」
出了什麼問題？ 該類所做的幾乎是將NPC的unpackack定義讀取並打包到一個文件中，但它沒有正確打包。 （請參見下面的格式，我使用）

不具有你去這裏，亞歷克斯，但該變量，正確的說法是'splitLine' 。動詞「split」的過去式實際上是「拆分」，如「我昨天分割日誌」。你似乎試圖使用不是英文單詞的「splitted」，並且在任何情況下，你都錯過了一個't'，這將使得基本單詞「splite」，而不是英語中的一個。無論如何，與這個問題完全無關，我只是一個學生:-) – paxdiablo 2012-02-14 01:12:17
